.35 Remington
Is a big stick in a small package. The effect on game is much more than the paper ballistics would indicate. It just has to be seen to be believed. Deer, great. Pigs too, I would think.
Way back when, before WWII, Remington had a line of cartridges (and rifles) to compete with Winchester. .25 Rem vs .25-35 Win, .30 Rem vs .30-30 Win, .32 Rem vs .32 Win Spl, and then there was the .35 Remington. The Remington rounds were all rimless, and were chambered in bolt, pump, and autoloader rifles. All the smaller rounds have faded away, but the .35 rem still lives on. I think for two main reasons. One, it does it's job very well. and Two, the Marlin lever gun. T/C Contenders have expanded it's popularity beyond the northeast woods, and that is a good thing, but it is not what has kept the round from fading away in the face of more modern competition.
For many years, the .35 Rem was the biggest thing you could get in a new production lever gun, and only Marlin made it. Until the .444 was introduced, amd the .45-70 re-introduced, the .35 was king of the woods.
before you get the impression that I am a huge fan of the .35 rem, let me say that I don't own one. I have a .30-30, and a .45-70. So I have no need of the .35 Remington. But I do respect it. My uncle carried one for years, and it always delivered. The new Hornady ammo will only make it better.
